Component specifications
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
The component specification gives the value of the component when the connector is disconnected. Where no value is given, it is not possible to measure a relevant value at the component.
The graphic within the brackets indicates the terminal pin on the component to which the value refers.
